News like this makes me so nostalgic for the PSP homebrew and "hacking" scene of the 00's. It's what got me into software in the first place.
My reason for starting with that scene was to play my "backed up" games but I remember screaming with joy when I got a C++ program onto the PSP which displayed some colours and bars. I could change them with the buttons and joystick.
I wish I could bottle up the magic that was the PSP homebrew scene and give it to kids today. I'm guessing Minecraft mods are the closest modern version.
I was just playing around with the Xbox Dev Mode this weekend and trying out different emulators.
